4-Butylresorcinol

Explained

Also known as Rucinol. It's an antioxidant primarily used to treat hyperpigmentation in the outermost layer of skin.

Hyperpigmentation occurs when an enzyme called tyrosinase triggers melanin production in the skin. Melanin is the pigment that gives skin, hair, and eyes their color.

Rucinol works by preventing tyrosinase from creating more melanin. According to a study from 2013, rucinol is more effective than other tyrosinase inhibitors such as hydroquinone, arbutin, and kojic acid.

According to a manufacturer, this ingredient is sensitive to air. Good formulations should account for this to keep your rucinol effective.
